I think I agree with everything on the topic that's been said thus far. It wasn't as much a question posed for advice as one of curiosity - how do other people, writers or not, feel about this?
Pkalata, you managed to explain a lot of how I feel about it far better than I was able to. What it comes down to, if I am to write stories in the world I'm considering, is that question of "Why?" Do I gravitate towards those classic races simply because this was developed initially for a D&D game (which it's never actually been used for), or is there more of a reason? If I am trying to break some of the tropes and stereotypes that come along with using those races, might I be better served by renaming them, retooling them, coming up with something different all together?
It all touches upon a thought that I probably didn't convey very well in my original post: ultimately, a character's race is just one small part of what defines him/her. We are all defined in some way by cultural, national, and ethnic backgrounds, but that alone does not define who we are. I think the backlash I've seen against these traditional fantasy peoples may be in response largely to writers who use the character's race as a crutch to lean upon, taking the lazy route instead of creating a unique, interesting individual with goals and desires and likes and dislikes who happens to also be a dwarf.
Tink, you also summed up my feelings quite well in your first paragraph. I was trying to get at just what you said, and ultimately the characters for this novel, whenever I decide to get to it, are already defined in my head regardless of what their race might be.
In response to the rest of your post, Tink, I am not currently writing (or maybe I am, now, but that's something that's only happened over the course of the last few days after a conversation with my wife over the weekend, which sparked some of my posts here). Most of the pieces I've written over the last few years have been short stories - I have one in each volume of Sojourn - and I have probably a half dozen of them in various stages of production, at least, and concepts for a handful more. I did hit a period where I was writing on my lunch breaks, and wrote something like three short stories in two or three days.
To proceed to talk about myself, my current plan of attack regarding writing in general is to get to those short stories. I have rewrites to do, and I have drafts that are incomplete, but I want to start getting them out to different markets again, like I had started to a little before Sojourn 1 became a thing. I'll use those to get myself into the habit, shake off some of the rust, and if I am lucky enough (or as skilled as I think I am) I might even pull a professional sale out of it.
The ideas for longer works aren't going anywhere, and I can start them at any time.
TL;DR: pkalata and tink333 are right, and I need to write.
Nobody expects the Spanish Inquisition!
